Ocean Health Index – Tanzania 2018 6
2.3. Applications of the framework, process and tool
The potential use of the Ocean Health Index as a framework to facilitate multi-sectoral discussions on
ocean use and management, and as a tool to track resource state, have been outlined in the table below
in four categories; data, planning, economy and country targets and references points,.

USES
1. Identify available local data as well as gaps in information; biological, governance,
social, pollution etc.
2. Improve data sharing via stakeholder collaboration
3. Improve access to data through a central repository
4. Increase data management skills and capacity in relevant local institutions
1. Bring forth diverse scenarios leading to adequate prioritization and integration of
stakeholder goals
2. Contribute to or support development of effective ocean policies, strategies, plans and
regulations.
3. Track effectiveness of management interventions to achieve targets and improved
ocean health
4. Identify management and funding priorities for investment
5. Implement Sustainable Development Goals
1. Inform on areas to invest; allocate funds for sustainable resource exploitation
2. Ignite initiation of dialogue on resource allocation
1. Assist the country in setting targets and reference points at attainable scales.
2. Streamline national and sub-national development reporting procedures
3. Establish targets and evaluate the effectiveness of interventions
3. Methodology
3.1. OHI Framework
Methods for calculating the OHI were developed at a global scale and released in 2012, combining dozens
of data sets to produce annual Index scores for coastal nations and territories (Halpern et al., 2012). The
global analysis has been repeated annually with a focus on improving methods and data (Halpern et al.,
2017, 2015; Lowndes et al., 2017; ohi-science.org, 2017). The OHI identifies 10 goals that encompass
ocean health: Food Provision, Natural Products, Clean Water, Coastal Protection, Carbon Storage,
Biodiversity, Tourism & Recreation, Livelihoods & Economies, Artisanal Fishing Opportunities, and Sense
of Place (Fig. 1). These goals are scored on a scale of 0-100, reflecting how well coastal regions are
optimizing their potential ocean benefits and services in a sustainable way relative to a reference point: a
score of 100 indicates optimal sustainable achievement of a goal target. For full, current global methods,
